IMPROVEMENT IN CARvING--MACHINR The Schedule referred toin these Letters Patent and making part of the sama.

To all whom it may conce/rn.-

Be it known that I, ADOLPH HENKEL, ofthe city, county, `and State of New York,'have invented a new and useful Improvement iu Carving-Machines, of which the following is a. full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification, and in which- Figure 1 represents a top view or plan of a carvingmachine, constructed in accordance with my invention igure 2, a longitudinal vertical section of the same; an

Figure 3, a transverse section thereof', through the line a: x, in fig. 2, and looking in direction of the arrow z.

Similar letters of reference indicate corresponding parts.

My improvement relates to carving-machines, in which the cutter, or reducing and carving-tool hasits -aetion on or over the werk, or body, to be carved, regulated, and directed by the travel of a tracer on or over a pattern corresponding in form` to the desired configmation of the carved surface, or article to be inade.

Said improvement is applicable to carving on different kinds of material, and for doing different sorts of work, including vlars-reliefs, busts, 85e., and is capable of carving work either larger or smaller than the pat tern with which the work, as regards 4shape of outline, made to coincide by the travel or action of the tracer.

In this connection, the invention includes a horizontally and vertically-swinging arm, carrying an adjustable tracer and rotating carving-tool, arranged over the work and pattern, which are hung on centres connected with swinging carriers, pivoted to head-stocks that are made capable of a joint sliding movement at different velocities, the whole providing for auniversal adjustment of the work and pattern, and of varying the size, or proportions ofthe work to the pattern in a most perfect and practicable manner.

Referring to the accompanying drawing- A represents the frame of the machine, which may be of any suitable form.

Said frame carries at its one end a standard, B, on which is mounted a driving-pulley, C, and which serves to carry, by trunnions a, at opposite ends, a cross-rocking shaft, or beam, D.

This rocking-shaft, or beam D, has connected Awith it, and serves to carry, by a vertical pivot, l), a forwardly-projecting, or extending tracer, and carvingtool arm, or lever E, having a longitudinal slot, c, in it, along which the tracer F and1 rotating carving-'tool G, or the holders thereof, are adjusted, and their proper set, rel tively to each other, determined by a scale, or graduated surface, d, on said arm, according to the size the carved work is required to bear to the pattern.

As the tracer F and carving-tool G are here arranged, the work will be cut, or carved larger than the pattern, but by reversing the positions of these devices; that is, placing the tracer forward of the carving-tool, the work will be cut smaller than the pattern.

1t will suffice here, however, to describe "the operation` of the machine, with the tracer and carving-tool arranged as shown.

llhe arm E, carrying these devices, is, by the hang of it, as described, free to swing both vertically and horizontally, in order that the tracer may follow, or tr. vel over the pattern, and the carving-tool have corresponding movements, Athough differing in degree, given it to cut or shape the work according, as regards outline or configuration, to the pattern. Said arm is moved laterally by the operatorin attendance, tomake the tracer follow the pattern and carving-tool travel over the surface, article, or body to be carved, the free hang of said arm to adjust itself vertically, serving, at the same time, to allow of these devices-rising and falling automatically, according to the outline ofthe pattern.

The pattern is hung in. adjustable centres e el, arranged to project inwardly from or through slides H H1, adjustable along slots ff, made in a carrier-I, which is pivoted, as at g, so as to admit of its rocking or swinging vertically, in reverse directions, simultaneously on opposite sides of said pivot, by which arrangement the pattern is capable of a varied set in a crosswise direction of the machine, relatively to the tracer, and may be made to assume either a horizontal or angular position, in reverse-directions, by swinging the carrier to raise or lower either centre, e e, according to the general or special conliguration of the pattern.v

This angular set is regulated by means of a curved scale, h, attached to said carrier, and operating in connection with a fixed pointer, or pin, i, attached to a head, or head-stock, J, arranged on the bed of the machine, and to which the carrier I is pivoted for action, as described.

Provision is also made for turning the pattern in an axial direction on its centres e c, by means of a slotted arm, or sub-carrier, 7c, attached to the one centre-pin, e; and arranged to gear with a pin projecting from the pattern', such turning, or turned set of -the pattern being regulated `or determined by an index-plate, l, on the back of the centre-pin e, operating in conjunction with a fixed pointer, m.

The head-stock J is also adjustable along the bed of the machine, as hereinafter described.

The work, article, or body to be carved is similarly held and made adjustable by arranging it on centres e2 e?, projecting from slides H2 H3, adjustable along slots made in a carrier, I', pivoted as at y', and provided with a curved scale, h', operating in connection with a fixed pointer, or pin, the one centre-pin, falso being provided with a slotted arm, or sub-carrier, lo', that gears with a stud in the end of the work, and said centre-pin, furthermore, being provided with an indexplate, l', operating in conjunction with a fixed pointer, m.

By means of the index-plates l l', uniformity in the cording to the relative proportions of' the work and axial set of' the Work and pattern is secured, While, by pattern, the head-,stocks J and J are made to travel, means of the curved scales 71I h', their angular set across on turning the screw L, along the hed, in the same relthe machine is made to conform. ative ratio as the pattern bears to the work, by reason Both head-stocks J J are made conjointly adjustaof the action of the screw L on the head-stcck, J bein ble, or made to slide along the bed ofthe machine, but a direct one, while the movement given through it to in a variable or unequal manner; that is, in the same the headfstockJ is an indirect one, and as much slower ratio, as regards speed or distance, as that which the as the pattern is smaller than the work. pattern and work bear to each other, in point of size In each and all of these several movements of the or proportion, and whereby, in the travel of the work tracer and carving-tool over the pattern and work, and and pattern longitudinally, in relation to the bed, as of the latter under said tools or devices, the carving- Well as in the movement, or movements of the arm E tool is rotated or driven, to effect the necessary cut or over 4the work and pattern, the same relative actions reduction, by means of a belt running from the drivingofthe tracer F and carving-tool G, to accord with the pulley C to a pulley, C', on the upper end of the carvdifference in proportions of the Work and pattern, are ing-tool G. preserved in every direction. What is here clail This relative travel ofthe head-stocks J J carrying` Letters Patent, isv the Work and pattern, is effected by turning in either The combination, with the horizontally and vertidireetion, as required, a screw, L, that gives motion to cally adjustable, or swinging arm E, carrying the tracer the head-stock J', which is connected to the head-stock and carving-tool, of' the head-stocks J J the screw L, J by a rod, M, through the intervention of a lever, N, the rod M, the graduated lever N, the rod O, and the ned, and desired to be secured by c and rod O. l graduated plate P, essentially as described.

This lever N, pivcted as at lr, is graduated on its ADOLPH HENKEL. face, as is also the plate P, attached to the head-stock lVitnesses: J, so that on inserting the rod O, or its duplicate, of FRED. HAYNES, different length to suit, in any ofthe holes s s', having HENRY T. BROWN.
